Pete is vulnerable to slag, which can dramatically reduce the time it takes to kill him. A nova explosion cannot be avoided except by putting distance or an obstacle between Pete and the character even the Phalanx Shield from Axton's Sabre Turret will collapse before the explosion is finished. Characters must be nearly on the other side of the arena for Pete's nova explosions to miss them, and if they occur near the center of the arena then it is unlikely that there is any safe area. While avoiding the status effects entirely is desirable, it is also usually impossible owing to the large blast radius of each nova explosion.

If frequent use of the valves cannot be avoided, spawning high-level spiderants is preferable to high-level rats, as the player need only keep their distance from the former.

Alkaline/Inflammable shields will also prevent status effects from occurring outright if worn during the nova. A Booster Shield with even a trivial chance to drop a booster can help with this, as the damage from the status effects qualifies for triggering a booster drop, but the Big Boom Blaster is an optimal choice. Allowing the corrosion or fire effect to last long enough for Pete to set off a second nova explosion is recommended if possible, as one use of the valve will extinguish both status effects, as well as providing appropriately leveled targets for getting second winds. Rat or spiderant level increases are capped at 14 levels above Pete, and at such high levels can even pose more of a threat than Pete himself. Management of the burn and corrosion status effects Pete inflicts must be done carefully, as extinguishing the status effects using the nearest valve will cause the enemies spawned by each valve to level up three levels at a time. Axton's Sabre Turret, Zer0's Decepti0n hologram, or Gaige's Deathtrap can be useful for this purpose, as like other raid bosses Pete will prioritize attacking these targets when they are present rather than the character. Keeping a good distance between Pete and the Vault Hunters is vital, both to avoid his sweeping flame/acid attacks, as well as maximizing the small chance that the character will be outside the range of his periodic nova explosions. The battle against Pete takes place at Pyro Pete's Bar, and is fairly straightforward, if particularly lengthy due to his high health and strong shield. Use Raid Post to spawn Pete the Invincible.
